Device for the control of a light beam in a large angular range, and its use in a detecting device

摘要

the control system of the direction of a light beam includes the following main elements substantially aligned with the direction of a laser beam emitted by a source (1).a deflection device (2) operated at low du00e9viau00adtion.a holographic multiplexer (3) containing several areas recorded and provides several possible deviations in the direction of the beam which it receives.a system of valves (4) to determine the direction of the laser beam to emit.;this device is in a large scope anguu00adlaire deflect a laser beam.
